Intel® VTune™
Installation on a Linux* System

A self-check script is available to validate that appropriate drivers are installed and the system is set up properly to collect performance data. The script can be run on individual systems or on a cluster environment.
script is available from
on the Linux system on which
is installed. The script runs several representative analysis types on a sample with reliable hotspots. After the script completes, it produces a log file and gives diagnostics on the success or failure of the checks. The analysis types that are launched cover:
  • Software sampling and tracing collection (Hotspots in the
    user-mode sampling
    mode or Threading)
  • Core event-based sampling collection (Hotspots in the
    hardware event-based sampling
    mode with and without stacks)
  • Microarchitecture Exploration analysis
  • Memory Access analysis with uncore events
The diagnostics detect possible collection limitations and lists steps to overcome the limitations. The output also provides information about missing permissions or outdated drivers.
Use the
option when running the script to specify a location for the log file to be stored. This option is useful when running the script on a compute node through a job scheduler.

Product and Performance Information


Intel's compilers may or may not optimize to the same degree for non-Intel microprocessors for optimizations that are not unique to Intel microprocessors. These optimizations include SSE2, SSE3, and SSSE3 instruction sets and other optimizations. Intel does not guarantee the availability, functionality, or effectiveness of any optimization on microprocessors not manufactured by Intel. Microprocessor-dependent optimizations in this product are intended for use with Intel microprocessors. Certain optimizations not specific to Intel microarchitecture are reserved for Intel microprocessors. Please refer to the applicable product User and Reference Guides for more information regarding the specific instruction sets covered by this notice.
